KUDOS SK-12C Heavy-Duty Floor-Standing Ultrasonic Cleaner with LCD Control Panel

Overview

The KUDOS SK-12C is a heavy-duty, floor-standing ultrasonic cleaner engineered for consistent, high-efficiency cleaning of laboratory glassware, precision components, medical instruments, and industrial parts. It operates on the principle of cavitation—generated by high-frequency mechanical vibrations transmitted through a liquid medium via piezoelectric transducers—to dislodge particulate contaminants, organic residues, and biofilms from surfaces without mechanical abrasion. With a nominal frequency of 25 kHz, the SK-12C delivers robust low-frequency energy ideal for removing tenacious soils from complex geometries and heavily soiled items. Its 26-liter stainless steel tank (AISI 304) supports batch processing of large or multiple samples, while its integrated heating system—coupled with ultrasonic energy—enhances detergent activation and accelerates soil solubilization. Designed for continuous operation in QC labs, R&D facilities, and maintenance workshops, the unit meets foundational requirements for reproducible cleaning validation under GLP-aligned workflows.

Key Features

• Intuitive backlit LCD control panel enabling simultaneous real-time monitoring and adjustment of time, temperature, and power output
• Precision power regulation from 40% to 100% in 1% increments—enabling method optimization for delicate versus rugged substrates
• Digital timer with 1–199 minute range and automatic shutdown for repeatable process control
• Programmable temperature setpoint between 20 °C and 60 °C, with real-time display of actual bath temperature
• Ultrasonic-assisted thermal uniformity: acoustic energy promotes convective mixing, minimizing thermal gradients across the tank volume
• Dry-run protection circuitry that halts heating and alerts operator upon detection of insufficient fluid level
• Non-volatile memory retains last-used parameters after power interruption—ensuring protocol continuity during scheduled maintenance or outages
• Twelve high-reliability piezoelectric transducers mounted on the tank bottom ensure broad acoustic field coverage and long-term operational stability

Sample Compatibility & Compliance

The SK-12C accommodates a wide range of sample types including volumetric flasks, burettes, pipette tips, surgical forceps, dental tools, printed circuit boards, and optical lenses. Its 304 stainless steel tank resists corrosion from common aqueous cleaning solutions (e.g., alkaline detergents, enzymatic formulations, and mild acidic rinses), supporting compatibility with ISO 15883-1 (washer-disinfectors) and ASTM D2603 (ultrasonic cleaning performance evaluation) reference practices. While not certified as a medical device under FDA 510(k) or CE IVD, the unit is routinely deployed in environments adhering to ISO/IEC 17025 and GMP Annex 15 cleaning validation frameworks—particularly where documented parameter traceability and repeatability are required. Its open architecture allows integration into lab-wide asset management systems via manual log entry or external data capture.

Software & Data Management

The SK-12C operates via embedded firmware with no external software dependency. All operational parameters—including start time, duration, set temperature, applied power percentage, and elapsed cycle time—are displayed and adjustable directly on the LCD interface. Though it does not feature USB, Ethernet, or RS-232 connectivity, its digital timer and parameter memory function support basic audit trail generation when combined with lab notebook documentation or LIMS-based entry protocols. For regulated environments requiring electronic records per FDA 21 CFR Part 11, users may deploy external time-stamped video logging or integrate the unit into broader facility monitoring systems using discrete I/O triggers (e.g., relay closure at cycle completion).

Applications

• Routine decontamination of reusable labware prior to sterilization or analytical use
• Preparation of samples for SEM, TEM, and surface metrology by eliminating sub-micron particles
• Cleaning of calibration standards, reference materials, and sensor housings to prevent cross-contamination
• Removal of flux residues from PCB assemblies in electronics manufacturing QA
• Supporting ASTM E1473 and ISO 11140-5 test methods for verifying cleaning efficacy of medical devices
• Assisting in pharmaceutical equipment cleaning validation studies where sonication is specified as a critical step

FAQ

Is the SK-12C suitable for cleaning delicate optics or MEMS devices?

Yes—when operated at reduced power (40–60%) and lower temperatures (20–35 °C) with compatible low-foaming, non-ionic detergents, it has been validated for cleaning fused silica windows and microfluidic chips without surface pitting.
Does the unit comply with electrical safety standards for laboratory use?

It conforms to GB 4793.1 (equivalent to IEC 61010-1) for electrical safety of laboratory equipment, with double-insulated construction and grounded chassis design.
Can the tank be filled with solvents other than water-based solutions?

No—only aqueous cleaning solutions are recommended. Organic solvents may degrade seals, damage transducers, and pose fire hazards due to lack of explosion-proof certification.
What maintenance is required to sustain optimal cavitation performance?

Monthly inspection of transducer mounting integrity and quarterly descaling of the tank interior using 5% citric acid solution at 40 °C for 30 minutes is advised.
Is calibration documentation provided with the instrument?

Factory calibration certificates for timer accuracy (±0.5%) and temperature sensor linearity (±1.0 °C over 20–60 °C) are available upon request at time of order.
